Definitions

  • the invention relates to an outlet, in particular a ceiling air outlet, for supplying cold and / or warm air into a room, the air being able to be guided via a connecting piece into an opening provided with openings, which has a base surface designed to let the air out.
  • the cold air is generally blown horizontally and the warm air vertically into the room.
  • These air outlets have a front plate with a plurality of individual openings, behind which air deflection elements are arranged which, by rotation, bring about a change in direction of the individual jets.
  • Versions are also known in which guide vanes which are variable in the angle of attack are arranged in the outlet plane or shortly before.
  • the known air outlets can be adjusted manually as well as electrically or pneumatically, the free flow cross-section being changed greatly due to the design when switching from the horizontal jet to the vertical jet. An application in the industrial area with the requirement of large volume flows is therefore problematic.
  • an air outlet with a housing is known, in the wall and base plate openings of which the overall size is primarily the same.
  • the housing is assigned an insert with openings arranged offset and almost identical to the openings in the housing, so that the free flow cross section of the openings of the housing can be changed by rotating the insert.
  • the openings in the wall of the housing are completely free and the openings in the base plate are completely closed or vice versa.
  • the free areas of the side openings are changed in opposition to the free areas of the bottom openings.
  • the invention has for its object to design an outlet of the type shown so that both cold and warm air can be easily controlled in a room, in addition to the pure horizontal or vertical jet, all intermediate jet directions are adjustable and impermissible thermal Layers are degradable.
  • the bottom surface is divided, the individual elements being arranged individually or in their entirety so as to be displaceable and / or pivotable.
  • the individual elements can be assigned horizontal axes that run through the center of the floor surface or end in the center.
  • a support for the individual elements of the bottom surface is arranged at the lower edge, wherein the support can be formed by an annular disk.
  • each individual element of the floor surface is connected to a vertically displaceable carrier via at least one rigid connecting element.
  • a drive is expediently assigned to the vertically displaceable carrier, which is formed by an electrically or pneumatically drivable motor. There is also the option of forming the drive using a control mechanism with manual adjustment.
  • the outlet has a connecting piece 1, which is provided with a lower collar 4 in the form of an annular disk 5 which is angled outwards and the outer edge of which is angled downwards.
  • the upper outer boundary of the housing 2 adjoining at the bottom bears against this angled edge.
  • the cross-sectional area of the housing 2 is larger than the cross-sectional area of the connecting piece 1.
  • the housing 2 has the shape of a circular cylinder 4, the outer surface of which is provided with rectangular openings 3.
  • the shape of these openings 3 and the shape of the housing 2 and the connecting piece 1 can be carried out as desired.
  • the cross-sectional area of all openings 3 is larger than the cross-sectional area of the connecting piece 1.
  • the bottom surface of the outlet is formed by four quarter-circle-shaped individual elements 6, which are each rotatably mounted on a horizontal axis 7.
  • the horizontal axes 7 run radially outwards from the center of the base surface.
  • the individual elements 6 are connected with an edge to the associated horizontal axis 7, so that the individual elements 6 can be pivoted inwards and the individual elements 6 do not protrude from the plane of the housing 2 after the pivoting.
  • the shape of the individual elements 6 is determined by the cross-sectional shape of the housing 2, the size of the individual elements 6 being freely selectable.
  • a support in the form of an annular disc 5 is arranged on the inner side of the wall of the housing 2 at the lower edge. The width of this circular disk 5 is equal to or less than half the difference in the diameter of the housing 2 and the connecting piece 1.
  • the individual elements 6 of the floor area are connected via rigid connecting elements 8 to a vertically displaceable support 9, to which a drive 10 is assigned.
  • the ends of the connecting elements 8 are articulated.
  • the individual elements 6 lie on the circular disc 5 and form a closed bottom surface.
  • the air supplied to the housing 2 via the connecting piece 1 exits through the openings 3 perpendicular to the inflow, the exit speeds and the jet thickness being determined by the size, shape and arrangement of the openings 3 for a given volume flow.
  • the horizontal jets mix intensively with the ambient air and cause rapid temperature and speed reduction.
  • the bottom surface is essentially completely open, so that all the air supplied to the housing 2 emerges vertically. Due to the flow and pressure conditions generated in the housing 2, room air is drawn in via the openings 3, so that induction already takes place in the housing 2.
  • the annular disk 5 causes a more or less constriction of the beam in the exit plane depending on the width of the annular disk 5, which affects the exit velocity and thus the vertical penetration depth of the jet.
  • the housing 2 has the shape of a hexagon in cross section.
  • the individual elements 6 of the floor area are connected via rigid connecting elements 8 to a vertically displaceable support 9, to which a drive 10 is assigned.
  • Adjustable openings 3 are assigned to the openings 3 of the housing 2, which are arranged vertically in the interior of the housing 2 according to FIG.
  • a screen 12 serves as the lower limit of the housing 2.
